Ingest Splunk HEC events

POST/services/collector/event

Ingest one or more Splunk HEC event envelopes. Bodies may contain multiple envelopes, concatenated or newline-delimited. The target dataset is resolved from the index query parameter, then the index field of the first event, then the dataset the token is scoped to when it grants ingest access to exactly one dataset.

Use this endpoint to ingest events through the Splunk HTTP Event Collector (HEC) compatible API. For a walkthrough, see Send data using the Splunk HEC API.

The base domain for this endpoint is hec. prefixed to the base domain of your edge deployment. For example, if your edge deployment’s base domain is us-east-1.aws.edge.axiom.co, the HEC endpoint is https://hec.us-east-1.aws.edge.axiom.co.

Edge deployment	Base domain for ingest and query
`US East 1 (AWS)`	`us-east-1.aws.edge.axiom.co`
`EU Central 1 (AWS)`	`eu-central-1.aws.edge.axiom.co`

This endpoint only supports API tokens. Personal access tokens (PATs) aren't supported. For more information, see Tokens.

Parameters #

Property	Type	Location	Description
`index`	`string`	`query`	The dataset (Splunk index) to ingest into. Overrides the `index` field in the event envelope.

Body #

A Splunk HEC event envelope.

application/json

Property	Type	Description
`event`	`unknown`	The event payload. When an object, its keys become top-level fields of the Axiom event. When a string, it is stored in the `_raw` field.
`fields`	`object`	Additional fields merged into the event.
`time`	`unknown`	The event timestamp, as epoch seconds, epoch milliseconds, or an RFC 3339 string. When omitted, Axiom assigns the ingest time.
`index`	`string`	The dataset (Splunk index) to ingest into. The `index` query parameter takes precedence.
`host`	`string`
`source`	`string`
`sourcetype`	`string`
